Webchirp: [verb] to make a chirp or a sound resembling a chirp. WebIn pulse compression radar the transmitted bandwidth is a measure of the range resolution. Range resolution in radar is inversely proportional to the transmitted signal bandwidth. The stepped chirp waveform splits the full bandwidth linear frequency modulated (LFM) chirp into a sequence of narrow-band sub-chirps, which may overlap in frequency.
